I read all ten pages of the first thread above - and still come to the conclusion ATP is an excellent, torque happy kit.

A user posted his 420+ tq curve on pump with ATP's older 3071 kit. I dont see anything that says ATP is crap except for a few comments from a handful of posters based on their opinion.

Even the curve comparing Shiv's kit to ATP's look very similar.

 

Here is a post from someone who had both the Vishnu kit and the ATP kit:

Perhaps some of you can pm SHiv or even call Vishnu up and ask. SHouldn't take but a few minutes of your time. IIRC, they were going to carry the ATP kits until they got some numbers back and spool characteristics. That is why they chose to pursue an adaptor to run a GT30 turbo with the standard Garrett housing.
